Data Sheet
2-274
Timing is over recommended temperature & power supply voltages.
Typical figures are at 25
°
C and are for design aid only: not guaranteed and not subject to production testing.
* High Impedance is measured by pulling to the appropriate rail with R
, with timing corrected to cancel time taken to discharge C
.
** Individual writes to Connection Memories will have Register Acknowledgment Delay. Burst writes to Connection Memories will have Read
Connection Memory Acknowledgment Delay.
AC Electrical Characteristics
- Intel/National- HPC Multiplexed Bus Mode
Voltages are with respect to ground (V
